The title compound, C 43 H 45 NO 12 , was prepared from the reaction of 2,6-bis­(dibromo­meth­yl)pyridine and bis­phenol in the presence of caesium carbonate as a base. The central ring makes dihedral angles of 64.83 (6), 13.48 (6), 56.96 (6) and 66.21 (6)° with the peripheral rings. In the crystal, mol­ecules are linked by weak C—H⋯O and C—H⋯π inter­actions, forming a folded structure.
